A one-line Linux system report for explaining benchmark differences between machines.
When the same benchmark gives different numbers on two computers, the cause is rarely just "this CPU is faster". It is often the power source, the power profile, a hybrid P-core/E-core scheduler, a missing SIMD extension, or background load. This report puts all of that in one table, so you can paste it next to your results.
It is read-only. It only reads /proc and /sys and runs lscpu, free, df, lspci, nvidia-smi, powerprofilesctl get and dmidecode -t memory. It changes nothing on your system. Missing sources print n/a instead of failing.
Linux only. Works in bash and zsh.
